Answer:
There is this property called CATENATION which is basically the tendency of the atoms to bind to eachother. It is the MOST in the carbon after that silicon.
So the answer should Carbon atoms bond together to form groups of compounds.
Answer:
Mostly abundant Coral reef ecosystem
Explanation:
We know that,
There are 7 ecosystem in puerto rico but the grouper fisher such as nassau grouper is one of them that present in coral reef ecosystem.
Nassau grouper fish is one of the grouper fish that present in puerto rico island. It is now announced as danger in the US, and as risk by the International Union for Conservation of Nature.
Hence, Coral reef ecosystem is the most abundant in Puerto Rico
500 water molecules and the remaining 500 O2 molecules. Remember the ratio of H to O in H2O.
Number of photons can be calculated by dividing the needed energy by the energy per photon.
The minimum energy needed is given as 2 x 10^-17 joules
Energy per photon = hc / lambda where h is planck's constant, c is the speed of light and lambda is the wavelength
Energy per photon = (<span>6.626 x 10^-34 x 3 x 10^8) / (475 x 10^-9)
= 4.18 x 10^-19 J
number of photons = (2 x 10^-17) / (4.18 x 10^-19)
= 47.79 photons which is approximately 48 photons</span>
